Specification of Letters Patent;

Patented Sept. 17, 1907.

Application filed April 13, 1907. Serial No. 367,948.

To all whom it may concern:

Be it known that I, WILLY PE'rERs, a subject of the German Emperor, and a resident of Birkenstrasse 8, Dusseldorf, Germany, have invented certain new and useful Improvements in Dye-.liggers with Divided Vats, and Automatic Introduction of Dye-Baths, of which the following is a specification.

The dyeing of cloth is carried out to a large extent by means of the jigger process. Applicant believes however that for dyeing long pieces of cloth satisfactory results were first produced when the practice of adding the prepared dye liquor from the beginning onwards in the right quantity and strength for the particular piece to be dyed, to the jigger vat itself, was discontinued, and instead the dye bath previously made up in a special tank was gradually introduced from the beginning onwards in the perfectly empty or only par- 7 tially filled jigger vat, while the cloth passed through at the same time with increasing velocity. In practice it has been shown that the last mentioned process could be-carried out to advantage when the vat serving for making up the dye-liquor stood on a platform and the jigger itself was erected on a lower level; the dye liquor therefore flowed from the higher situated dyeliquor vats into the jigger vats situated lower down, spurted out of the perforated tubes on to the cloth running through the jigger and collected on the bottom of the jigger gradually filling the same. In order to make use of the weakened dye liquor it was necessary to pump the dye liquor back from the jigger vat into the higher situated reservoir; the same was also the case when the dye-liquor run into the jigger vat turned out too weak and the dyed piece did not receive the right shade and had to be again passed through the jigger. Besides these drawbacks and deficiencies, which result particu larly in loss of time, material and wages the high cost of manufacture of such installations has to be considered, the separate arrangement of the supplementary vat and the jigger takes up much space and a matter of great disadvantage in a dye-works, much light is lost owing to the raised position of the separate dye-liquor vat.

The present invention relates to a new full-width dyeing machine constructed and Working in the manner of the so-called jigger for uniformly dyeing cloth in which the entire dye-liquor is introduced into the jigger vat, and the cloth during the whole operation dips equally deep into the bath.

The most essential feature of this new full-width dy'eing-machine lies in the fact that the jigger vat contains several compartments, which together receive the same quantity of equally strong dyeliquor, which corresponds to the length of cloth to be treated; the latter is only led through certain compartments and to these the dye-liquor from the remaining compartment, or compartments is added by means of suitable devices during the passage of the cloth forwards and backwards.

It should be observed that hereinafter the term starting bat or starting dye-liquor-always refers to that quantity of dye-liquor through which the cloth is first led, before any liquor designated hereinafter as compensating dye-bath.or compensating dye-liquor from the other compartment or compartments is added.

The jigger vat is conveniently constructed so that the compartments containing the starting bath stand continually in communication with one another, but can also when desired be put into communication with the compartments for the compensating bath. This for instance is of advantage when the total dye-liquor is introduced or mixed.

The introduction of the compensating bath to the starting bath can be brought about by any suitable means. For example the space inclosing the compensating bath can be reduced, which may be carried out for instance by arranging the bottom, so that it can move, and connecting it with a device which operates the gradual, automatic, raising of the bottom. I11 this operation the compensating bath is made to pour uniformly over the compartment walls inclosing the same into the compartments for the starting bath.

In order to dye by means of the new jigger, the dyeliquor isfirst introduced in a quantity corresponding to the length of cloth to be treated, and strength corresponding to the shade to be produced in the jigger vat itself, at which time all the compartments communicate with one another. Then a part of the cloth being dealt with is led through the compartments containing the starting bath, dipping always to the same depth, and to this dye-liquor the compensating dye-liquor is gradually added from the other compartments. The cloth runs through in the Well-known manner with changing velocity.

It is advantageous to allow about a third of the cloth which may have a length of 1300 to 1600 yards to run through the starting bath, and then to begin with the introduction of the compensating bath in such a manner that about a third of the latter is distributed during the forward passage of the last two-thirds of the length of cloth, and in the passage backwards the remaining two-thirds of the compensating bath is distributed over the whole length of cloth. According to requirements the compensating bath can also be distributed in other Ways. i

In the drawing a form of construction of the new jigger is shown, and in this case the jigger has three compartments of which the middle one serves to receive the compensating dye-bath.

Figure 1 shows a section on line I-I of Fig. 3. Fig. 2 shows a sectionon line II-II of Fig. 3. Fig. 3 is a plan of the jigger showing parts of the construction omitted. Fig. 4-8 show single features of the jigger on an enlarged scale.

The jigger vat 1 is divided by the walls 2 and 3 into the compartments 4, 5 and 6.

The walls 2 and 3 have below openings 7, through which the compartments 4 and 6 are continually in communication with one another.

8 is the movable bottom of the middle compartment.

The driving of the winding rollers 10 and 11 is carried out by means of the belt-wheel 12. The rollers 10 and 11 are situated on the frame 9 so as to be capable of. being adjusted and interchanged in the well-known manner. The belt wheel 12 and idle wheel 13 are fixed on the main shaft 14, which operates the axles 19 and 20 through the bevel wheel gear 15, and 16, 17, and 18.

On the axle 19 a clutch'coupling 21 is fixed and on the axle 20 a clutch coupling 22. 23 is the lever having its fulcrum at 20 for operating these clutches, which is kept in the proper position for the time being by means of the slots 25 of the arm 26. These clutches 21 and 22 serve to make the cloth 66 run forwards or backwards according as the clutch 21 or the clutch 22 is switched in.

The movable bottom 8 which fits quite tight on the walls inclosing it and which can be made particularly tight by the application of felt strips 27 or the like is supported by the rods 28, 28 and 29, 29 which in the upper part at 30 and 31 are toothed. The toothed rods 30 engage with the cog wheels 32, the toothed rods 31 in the cog wheels 33. The former are fixed on the shaft 34, the latter on the shaft 35. Both of these shafts are dependently connected through the shaft 36 and the bevel gears 37, 38. They are driven from the main shaft 14 through the agency of the ratchet wheel hereinafter described.

On the one end of the shaft 34 there is a ratchet wheel 39 in which a pawl 40 engages (Fig. 4) which is fastened to the double arm 41 situated on the shaft 34 by means of the pin 46. The arm 41 is connected with the rod 42 which is adjustable in the slot 44 of the crank arm 45 by means of the pin 43 the crank arm 45 is fastened on the shaft 14. The crank 45 obtains its motion through the agency of the cog wheels 51 and 52 from the main shaft 14. Owing to the adjustability of the arm 42 on the crank arm 45, it is possible to move the ratchet wheel 39 any convenient number of teeth further at each revolution. The pin 46 is cut fiat at 47 and 48. The flat place 47 serves to hold the pawl 40 with the aid of the spring 49 in the position of engagement (Fig. 6) and to prevent the pawl fromautomatically turning so far down that it comes out of engagement. In the latter position which is necessary for instance on the lowering of the bottom 8, the pawl 40 is so held by the engagement on the fiat place 48 of the spring 49 (Fig. 7). 50 is a ratchet wheel fixed on the other end of the shaft 34, which with the pawl 53 belonging to it works against the tendency to rotate of the ratchet wheel 39 and prevents the bottom 8 from sinking of its own accord in the moment of the return of the pawl 40. The pawl 53 (Fig. 8) is fixed on the pin 55 having a fiat side at 54 and has a slot 56 in which a stamp 57 influenced by a spring is situated. This works together with the surface 54 so that the pawl 53 is continually held in engagement. If the pawl is thrown out of engagement the stamp 57 operates also so that the pawl is kept in this position. Use is made also of a special device for automatically disconnecting the ratchet mechanism 40, 41, 42 and 45 as soon as the bottom 8 has reached its highest position which is usually the case when its upper edge is on a level with the upper edges of the walls 2, 3. This device consists of the lever 58 which is fixed on the pin 46 carrying at the same time the pawl 40. Against the lever 58 one arm of the double lever 59 can come into engagement with a pin 60 which is fixed on the toothed rod lying nearest to the ratchet wheel 39. On the rising of the bottom 8, and therefore the pin 60, this gradually turns the double lever 59, which turns the one armed lever 58 and therefore the shaft 46 and the pawl 40 turn until the latter comes out of engagement with the teeth of the ratchet wheel 39.

The operation of the new jigger takes place as follows: On beginning dyeing the compartments 4, 5 and 6- of the jigger vat are completely filled with the dyeliquor. According to the position of the clutches 21 and 22 the cloth runs from one of the winding rollers 10, 11 over the guide rollers 62 and stretchers 63 to the other, and in doing so the cloth passes through the compartments 4 and 6 filled with the starting bath. When about one third of the whole length of the cloth has run off the one roller, the pawl 40 is put into engagement. The bottom 8 now moves slowly upwards with the aid of the crank 45, the arm 42, the double arm 41, pawl 40, ratchet wheel 39, the shaft 34, 35, and 36, the cog wheels 32 and 33 and the toothed rods 30 and 31 and the rods 28. The dye-liquor of the compensating bath contained in the compartment 5 now passes over continuously and uniformly into the compartments 4 and 6. The movement of the bottom is so regulated 'that when the cloth has once run off about a third of the compensating bath has been used. Then follows the changing of the clutch couplings by means of the lever 23, so that the cloth begins to run back. The bottom 8 is raised further until the running back of the cloth has finished and the compensating bath has been completely distributed out of the compartment 5 into the compartments 4 and 6. When the bottom 8 has attained the highest permissible position the pawl 40, as described above is thrown out of engagement. The dye-liquor now fills the compartments 4 and 6 and also since it enters through the openings 7 below, the compartment 5. If the dye-bath is to be used again, fresh dye-stuff can be added, and a uniform mixture produced in all three compartments. In order to work anew the bottom 8 is, after throwing the clutches '21 and 22 and the ratchet mechanism 40, 53 out of engagement, lowered by hand, for instance with the aid of a crank handle fixed at 64 on the end of the shaft 34 until it comes below the openings 7 so that the whole dyebath is in communication through the openings 7 and can be mixed up; by raising the bottom 8 a little way up the compartment 5 is then closed off from the compartments 4 and 6. The pipes 65 serve for pumping the dye-liquor in and out, for adding water, and when needed for heating up the dye-liquor by means of steam. I

A great advantage of the dyeing process by means of the new jigger is that the cloth always dips equally deep into the dye bath during the whole operation which is not the case with the rising bath used in similar processes. The dyeing itself is therefore more uniform, since the means usually available (acceleration or retardation of the passage) are not sufficient to equalize the difference in shade occurring in the piece of cloth with the rising bath owing to the varying depth to which the cloth dips. Since the jigger vat receives from the outset the Whole dye bath, special separate vats are therefore unnecessary and a great saving of outlay implant, and of space is made. The jiggers can as usual stand on level ground, so that light from all sides may freely have access. The installation of pumps for bringing back the dye-liquor into a higher vat is avoided. On account of this pumping back of dye-liquor being avoided considerable power and time is saved. The new jigger makes it also possible to leave several jiggers under the control of one workman.

A further advantage consists in the fact that color can be added to strengthen the dye-bath after the piece has once run completely through, without it being first necessary to pump the dye-bath into a raised tank. In every case the dyeing of the cloth is much more uniform and certain even with materials which rapidly take the dye out of the bath such as for instance, wool, silk and half silk, than the processes hitherto employed. The cloth led through at first receives in the starting dye-liquor a correspondingly deep shade, in that it withdraws the dye from the same. The dye liquor so weakened is during the further passage of the cloth strengthened by the introduction of compensating dyeliquor in the same proportion in which its dye is taken out, so that the cloth is uniformly dyed. Since towards the end of the passage of the cloth, on account of the increasing diameter of the rollers, the cloth running at the end remains a shorter time in the dye-liquor, a balance can be made in well known manner either by letting the rollers rotate more slowly, or by running the cloth back again in which case the velocity relations operate in the opposite direction.
